General Information

Executive Summary

Executive Summary:

This update resolves several newly discovered publicly and privately reported vulnerabilities. Each vulnerability is documented in this bulletin in its own Vulnerability Details section.

If a user is logged on with administrative privileges, an attacker who successfully exploited the most severe of these vulnerabilities could take complete control of an affected system, including installing programs; viewing, changing, or deleting data; or creating new accounts with full privileges. Users whose accounts are configured to have fewer privileges on the system would be at less risk than users who operate with administrative privileges.

Microsoft recommends that customers install the update immediately.

Security Update Information

Acknowledgments

Microsoft thanks the following for working with us to help protect customers:

• Greg Jones of KPMG UK and Peter Winter-Smith of Next Generation Security Software Ltd. for reporting the 
  Install Engine Control Vulnerability (CAN-2004-0216).
 
• Mitja Kolsek from ACROS Security for reporting the SSL Caching Vulnerability (CAN-2004-0845).
 
• John Heasman of Next Generation Security Software Ltd. for reporting the issue in Heartbeat.ocx for which a kill-bit has been set in this security update.
 

Obtaining Other Security Updates:

Updates for other security issues are available from the following locations:

• Security updates are available from the Microsoft Download Center: You can find them most easily by doing 
  a keyword search for "security_patch".
 
• Updates for consumer platforms are available from the Windows Update Web site.
 

Support: 

• Customers in the U.S. and Canada can receive technical support from Microsoft Product Support Services at 
1-866-PCSAFETY. There is no charge for support calls that are associated with security updates.
 
• International customers can receive support from their local Microsoft subsidiaries. There is no charge 
for support that is associated with security updates. For more information about how to contact Microsoft 
for support issues, visit the International Support Web site.
 

Security Resources: 

• The Microsoft TechNet Security Web site provides additional information about security in Microsoft 
  products.
 
• Microsoft Software Update ServicesMicrosoft Baseline Security Analyzer (MBSA)
 
• Windows Update 
 
• Windows Update Catalog: For more information about the Windows Update Catalog, see Microsoft Knowledge 
  Base Article 323166.
 
• Office Update 
 

Software Update Services:

By using Microsoft Software Update Services (SUS), administrators can quickly and reliably deploy the latest 
critical updates and security updates to Windows 2000 and Windows Server 2003-based servers, and to desktop 
systems that are running Windows 2000 Professional or Windows XP Professional.

For more information about how to deploy this security update with Software Update Services, visit the 
Software Update Services Web site.

Systems Management Server:

Microsoft Systems Management Server (SMS) delivers a highly-configurable enterprise solution for managing 
updates. By using SMS, administrators can identify Windows-based systems that require security updates and 
to perform controlled deployment of these updates throughout the enterprise with minimal disruption to end 
users. For more information about how administrators can use SMS 2003 to deploy security updates, see the 
SMS 2003 Security Patch Management Web site. SMS 2.0 users can also use Software Updates Service Feature Pack to help deploy security updates. For information about SMS, 
visit the SMS Web site.

Note SMS uses the Microsoft Baseline Security Analyzer and the Microsoft Office Detection Tool to provide 
broad support for security bulletin update detection and deployment. Some software updates may not be 
detected by these tools. Administrators can use the inventory capabilities of the SMS in these cases to 
target updates to specific systems. For more information about this procedure, see the following Web site. 
Some security updates require administrative rights following a restart of the system. Administrators can 
use the Elevated Rights Deployment Tool (available in the SMS 2003 Administration Feature Pack and in the 
SMS 2.0 Administration Feature Pack) to install these updates.
